So I know what AC3 means of course, but what does AC3D mean in some releases?

It means Dubbed. It’s a short name for AC3.Dubbed
The audio track(s) have been dubbed to match with the video track.
The same applies to DTSD -> DTS.Dubbed
Is this different from mic-dubbed and line-dubbed? My impression was that those only come as mono or stereo, but many AC3D releases have surround sound.
Edit: So apparently dubbing is just the process of adding audio to a video track, sometimes replacing or complementing the original one. The quality dependends on where the audio comes from, but all of them are called “dubbed”.
If I had to guess, it stands for Definitive
AC3D is the Native file format naming of the AC3D program no doubt it’s for the word Dimension as in 3rd Dimension ie 3D
That was my first thought as well, but most of the releases I see are not 3D movies.
Who mentioned 3D Movies ?
